1Claim.

This invention relates to drinking devices in' he form of an open bottom beverage cup which 5 attachable directly to a bottle to constitute a nouthpiece and has for its object to provide a levice of this kind which can be applied, by slight IIBSSIJIG, to the end of a. bottle neck.

There are many people who either find it difll- :ult to drinkdirectly from a bottle or who do not ike to do so. The alternative is either a straw vr a separate container. The object of this inention is to provide a mouthpiece which will :ive an effect similar to drinking from a container r cup and which will fit the bottle end with sum- :ient security for use by children as well as adults.

Another object is to provide a bottle mouthpiece composed of a bottle gripping portion and :ide walls so arranged that contents from the )ottle cannot drain down the bottle sides upon 'eturning the bottle and mouthpiece to upright iosition after a drink.

Another object is to provide a mouthpiece, as lbOVG described, which is susceptible to tilting luring drinking through an angle greater than is )ossible with an ordinary cup whereby the head )f the user need not be tilted backward uncom- :'ortably.

v A further object is to provide a bottle mouth- .nafter more fully apparent as reference is had 'to ;he accompanying drawing wherein my invention 5 illustrated and in which,

Figure 1 is a side elevation of a bottle with my ,nvention applied thereto and illustrated in. sec

non,

Figures 2, 3 and 4 are axial sections of modified forms of the device, illustrating different bottle attaching portions, and t Figure 5 is an axial section of a further modi- Pied form showing a cut-out for nose room;

indicates a bottle having a neck 2 formed as is customary for beer and soft drink bottles and having a lip 3 rounded to receive a sealing cap; When the sealing cap is, removed the mouthpiece, forming the subject matter of my invention, is applied. It iscircular in any horizontal crosssection and has upwardly diverging side walls 4 which terminate inan internal conical portion 5 having upwardly converging walls. The part I mouthpiece on the bottle.

is a mouthpiece and the'portion 5 is a bottle neck engaging portion having less diameter than the greatest overall diameter of the top I of the bottle so that when it is forced down over the portion 3 it will engage the underside thereof and be retained thereon.

The material may be metal, paper or the like and when out with exactness it will be found that there is suflicient elasticity in the material itself to permit springing over the end 3 and then grippingthe bottle in the manner illustrated, in Figure 1.

Where the material is not cut with exactness, or whenever desired, the bottle engaging portion 5a may be crimped as illustrated in Figure 2 or it may be longitudinally serrated as indicated at 6 with regard .to the portion 5b of Figure 3. The forms of Figures 1 and 2 are preferred because when a bottle is tilted for drinking and then brought to upright position the cup formed by the two portions 4 and 5 is sufllciently large to hold all of the bottle contents left in the mouthpiece so that none of it drains down the bottle sides.

The capacity of the mouthpiece when uprighted may be increased by increasing the height of the bottle engaging portion, as illustrated in Figure 4. The sidewalls I converge to a height 8 and then diverge upwardly from the line 8 to form the top portion 9. The line '8 represents the portion which engages the region or line III of the bottle. The top edge ofthe portion 9 extends outwardly of the end of the bottle.

In Figure 5 a modified form of mouth portion I l is illustrated which has a cut out portion l2 to accommodate the nose of a user. This cut out makes it possible to provide less divergence of the walls of the mouth portion and hence requires less'material than the other forms illustrated.

What I claim is: The combination of a bottle havinga neck with opening in theend thereof, said neck having two circumferential beads of arcuate cross section adJacent said opening and correlated to form a groove at the juncture thereof,and a detachable mouthpiece-therefor comprising a mouth portion of frusto conical form and an inner part of frusto conical form 'with the small base of the mouth portion integrally united with the large base of the inner part, said inner part engaging a peripheral portion of the bead farthest remote from the opening and extending convergingly from its point of connection with the mouth portion toward the opening in the neck and into the groove between the two heads and having its end in abutting relation with the other head, said inner part comprising the sole means for supporting the ram w. mason).
